Persistence / MySQL should be disabled in Typo 3

[motin]

Currently Typo 3 tries to connect to MySQL during the benchmark:

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000] [2003] Can't connect to MySQL server on '127.0.0.1' (111)' in /public/typo3f-3.0/Packages/Libraries/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php:43

I tried to disable this via configuration but I must admit that I don't understand much of the Typo 3 documentation.

I stoped mysqld on my VM. But the error does not occur.

Just thinking that it may explain the notably bad benchmark results for typo3. If it is trying to connect to MySQL on every request in order to spell out a hard-coded "Hello World" it sure sounds inefficient :)
